Method Not Allowed (submit form with jQuery in Django)
I want to submit my "contact us" form on my Django website with jQuery. I'm working on development server. The error I receive in the browser and Django shell is: Method Not Allowed (POST): / Method Not Allowed: / [01/May/2023 17:08:34] "POST / HTTP/1.1" 405 0 This is my view: def is_ajax(request): return request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest' def submit_contact_form(request): if is_ajax(request=request): sender_name = request.POST.get('sender_name') sender_email = request.POST.get('sender_email') message_subject = request.POST.get('message_subject') message_body = request.POST.get('message_body') remote_addr = request.META.get('REMOTE_ADDR') remote_host = request.META.get('REMOTE_HOST') context = { 'from': sender_name, 'email': sender_email, 'subject': message_subject, 'message': message_body, 'IP': remote_addr, 'HOST': remote_host, } html_message = render_to_string('homepage/submit.contact.form.html', context) send_mail( f'Contact Form Submission: {message_subject}', f'{message_body}', 'myemail@mydomain.com', ['myemail@mydomain.com', ], html_message=html_message, ) return JsonResponse({}, status=200) else: return redirect('homepage:index') This is the jQuery code stored in a js file: $('#contact-form').submit(function(e) { e.preventDefault(); $('#sent-message').css("display", "none"); $('#loading').css("display", "block"); $.ajax({ type: "POST", url: "/submit-contact-form/", data: { sender_name: $('#name').val(), sender_email: $('#email').val(), message_subject: $('#subject').val(), message_body: $('#message').val(), csrfmiddlewaretoken: csrfToken, datatype: "json", }, success: function(){ $('#loading').css("display", "none"); $('#sent-message').css("display", "block"); $('#contact-form').trigger('reset'); $('#sent-message').delay(3000).fadeOut("slow"); }, error: function(){ $('#loading').css("display", "none"); $('#error-message').css("display", "block"); $('#error-message').append("An error has occured. Please try again later."); } }); }); As far as I can tell, this should work. I'm sure I'm making some stupid mistakes somewhere. Please assist. -

Django Q object - Is it possible to put those two queries together even if one depends from another?
Does anyone knows if is possible to put together two Q object queries in only one. Is the first time I need to use it and I am quite lost. First query: vendors = Vendor.objects.filter(Q(is_approved=True, user__is_active=True), user_profile__location__distance_lte=(pnt, D(km=1)) ).annotate(distance=Distance("user_profile__location", pnt)).order_by("distance") Second query: vendors = vendors.filter(Q(vendor_max_delivery_distance__gte=Distance("user_profile__location", pnt))) Can i make a function like a helper so I could call it whenever needs? Is it better to do it in models or contextprocessors? Thank you very much in advance!!! -
One db call when a ManyToManyField relationship is involved
I wish to implement an endpoint which returns a student's subjects, but only if they are not attending a private school. This is how I plan to do it: class Subject(Model): students = model.ManyToManyField() class Student(Model): subjects = model.ManyToManyField() school = model.ForeignKey(School) class School(Model): is_private = model.BooleanField() is_private = Student.objects.select_releated("school").get(student_id).is_private if is_private: raise Http403 return Subject.objects.filter(students__pk=student_id) So I am calling the database twice. Is it possible to do this in django by calling the database once and would it be more efficient to do so? Is there a use case for prefetch_related here? -
How to build an application that has a load balancer and 2 different servers
I have been stuck for a long and decided to ask for a advice I have to built an application that needs to have a load balancer and 2 servers. People want to know how to set up and test this application. My question is that if I run 2 Ec2 instances where I run this app, then do people need to create AWS account to test this application? If so, I would prefer them running this application in local environment where they use 2 servers How can I do this if I am using Django as tech stack? I am new and have been stuck forever but need an advice asap -
Improve performance of qs with multiple filters and exclude statements
I'm writing an app that has "social media capabilities". You can block someone you can wave to someone etc... I have get_queryset for getting all users you didn't see on the app or blocked them with multiple exclude and filter statements that look like this. def get_queryset(self): current_id = self.request.user.id blocked_users = Blocked.objects.filter(user__id=current_id).values('blocked_user') users_taken_action = UserWave.objects.filter(user__id=current_id).values('waved_user') users_not_taken_action = Profile.objects.exclude(user__in=users_taken_action) \ .exclude(user__in=blocked_users).exclude(user__id=current_id) return users_not_taken_action I'm new to optimization and when I see this function I get a feeling that this is not too efficient. Im wrong or is there a better way to handle this? models from django.contrib.auth.models import User class UserWave(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="current_user") waved_user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="waved_user") class Blocked(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="user_thats_blocking") blocked_user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="blocked_user") class Profile(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(null=True, blank=True) -

django-allauth twitter oauth2 Missing valid authorization header
Trying to setup a Django 4.2 app with django-allauth for Twitter using OAuth2. The user gets presented the Twitter Authorize page with the correct logo an account name but after the user clicks on the "Authorize App" button the following message is shown: Details: unknown, Error: Error retrieving access token: b'{"error":"unauthorized_client","error_description":"Missing valid authorization header"}' Any ideas on how to fix the Missing valid authorization header? The package versions are: django 4.2 django-allauth 0.54.0 The settings.py INSTALLED APPS 'allauth.socialaccount.providers.twitter_oauth2', I think settings in the Twitter API are setup properly as this Twitter App is being used successfully for non-Django operations (collect, tweet, etc). I've also double-checked the callback url which is the standard https://domain/accounts/twitter_oauth2/login/callback/ The Twitter docs https://developer.twitter.com/en/docs/authentication/oauth-2-0/user-access-token say for confidential clients (which this is, as it is a simple web app) the header should have Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ== I think the error message from Twitter is saying the request does not have the Authorization: Basic info . And I do not know how to set this up. Any help is appreciated. Cheers, Kevin -
HTML code won't load correctly using Django or Flask
Using the exact steps listed here, https://realpython.com/get-started-with-django-1/ and separately following tutorials for flask, I am able to run websites but the website itself always includes extra html codes, instead of simply "Hello, World!" On the website it says: <!doctype html> <h1>Hello, World!</h1> Why? I am saving my html file in a template folder. Using Django what is "translating the below"? Is it render? hello_world.html <!doctype html> <h1>Hello, World!</h1> I tried moving from flask to Django but same problem occurs. -

How to mock Django View methods?

Sending multiple mails to different recipients from Django Backend
I will do my best to explain the system clearly. Please read through the entire description, and if you have any questions, feel free to ask in the comments. The system I am building allows registered users to send invitations to multiple recipients with a single click of the submit button. In the invitation form, users can enter multiple recipients as a comma-separated string. When they click the submit button, they will immediately receive a notification indicating that the invitations were sent successfully. The backend will then communicate with the user through web sockets to update the status of each recipient's invitation from 'pending' to 'delivered.' (I have learned that a message queue or service worker is required in the backend to complete the email sending task asynchronously.) When the user submits the request, my view will create an invitation instance for each comma-separated recipient and call a function for the email sending task. Please take a look at my code for a better understanding. My views.py file: class InvitationCreateView(generics.CreateAPIView): queryset = Invitation.objects.all() serializer_class = InvitationSerializer def create(self, request, *args, **kwargs): title = request.data.get('title') message = request.data.get('message') recipients = request.data.get('recipients').split(',') invitation_ids = [] for recipient in recipients: recipient = recipient.strip() … -
How can I get only one field from Django Serializer?

Django_filter function attribute aren't showing on html page. Object is showing but not the form fields aren't showing
I am using Django_filter for the search operation. I created filters.py to create django filter and then inherited it into views to use it. I created myFilter object and send it to the forms. and if I use {{myFilter}} then it shows the <std_registration.filters.StudentFilters object at 0x000001538F850370> but if I use {{myFilter.form}} then it shows nothing instead of input fields. and it's not showing any error. Code: models.py: from django.db import models # Create your models here. class Student(models.Model): full_name=models.CharField(max_length=200,default="") gender=models.CharField(max_length=20) dob=models.DateField() address=models.TextField() state=models.CharField(max_length=100) image=models.ImageField(null=True,upload_to='std_registration/images/',default='') filters.py import django_filters from .models import Student class StudentFilters(django_filters.FilterSet): model=Student fields='__all__' exclude=['dob', 'gender', 'image'] views.py def display_view(request): student=Student.objects.all().order_by('full_name') myFilter=StudentFilters(request.GET,queryset=student) student=myFilter.qs return render(request,'std_registration/display.html',{'student':student,'myFilter':myFilter}) display.html <div class="row"> <div class="col"> <div class="card card-body" style="color: rgb(223, 255, 248);border: 5px;border-color: black;opacity:0.9;background-color: rgba(53, 53, 53, 0.4);"> <form method="get"> {% csrf_token %} {{myFilter.form}} <button class="btn btn-primary" type="submit">Search</button> </form> </div> </div> </div> remaining student record showing code....

djangosaml2idp logout throwing ServiceError exception: 'str' object has no attribute 'destination'

How to run tasks in django?
I have a Simple algorithm for testing that takes 2 numbers as an input and returns the sum as an output. I usually just write the algorithm in the view but i want to try an execute the algorithm as a task using ThreadPoolExecutor. My example: from concurrent.futures import ThreadPoolExecutor from django.views.decorators.csrf import csrf_exempt executor = ThreadPoolExecutor(max_workers=2) def my_algorithm(a, b): c = a + b return c async def run_algorithm_async(a, b): loop = asyncio.get_event_loop() result = await loop.run_in_executor(executor, my_algorithm, a, b) return result @api_view(['GET']) @csrf_exempt async def processTest(request): a = 1 b = 5 c = await run_algorithm_async(a, b) return Response(c) When i run it i get this error message: Expected a `Response`, `HttpResponse` or `HttpStreamingResponse` to be returned from the view, but received a `<class 'coroutine'>` What's seems to be the issue? and can i use the method for for more consuming dynamic programming algoritms?
